Summary
Sonography reveals characteristic biliary system changes in patients with fascioliasis (liver fluke infection). These findings, including moving echogenic structures, aid in diagnosing this parasitic disease.
Area of Science:
- Medical Imaging
- Parasitology
- Gastroenterology
Background:
- Fascioliasis is a parasitic infection affecting the biliary system.
- Accurate diagnosis relies on identifying characteristic imaging findings.
Purpose of the Study:
- To detail the specific sonographic appearances of biliary fascioliasis.
- To enhance the diagnostic capabilities of ultrasound in detecting this condition.
Main Methods:
- Retrospective analysis of abdominal sonography in 27 confirmed fascioliasis patients.
- Correlation of sonographic findings with serologic confirmation and surgical outcomes.
- Classification of sonographic findings into primary and secondary categories.
Main Results:
- Primary findings included mobile echogenic structures, linear/curvilinear echoes, and leaf-like structures within the biliary tree.
- Secondary findings involved biliary dilatation and wall thickening.
- Subcapsular liver nodules were observed in 14 patients.
Conclusions:
- Sonography is effective in visualizing biliary lesions associated with fascioliasis.
- Familiarity with diverse sonographic presentations is crucial for accurate diagnosis.
- Ultrasound can significantly aid in the diagnosis of biliary fascioliasis.

01:27Liver Histology
The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.

01:17Gross Anatomy of the Liver
The liver, the largest gland within the human body, is a firm and reddish-brown organ. This wedge-shaped structure weighs approximately 1.5 kg and occupies a significant portion of the right hypochondriac and epigastric regions. It extends more to the right of the body's midline than to the left.
Located under the diaphragm, the liver is almost entirely ensconced within the rib cage, providing it with substantial protection. Except for the superior most bare area, the liver's surface is covered...

IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...
01:20Ultrasound I: Abdominal Ultrasonography
Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

01:26Diseases of the Liver and Gallbladder
Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not related to...
